q TYPEWRITER-PAPER STOP.

My invention relates to an automatic Writing stop for usein typewriting.

The main object is to provide a simple, practical, and inexpensiveautomatic means to enable anyone using a typewriter to immediatelyascertain when the writing end' Another object is, to provide means ofadvertising'which will be constantly brought to the attention oftypists. I M

It usually requires two operations for a typist to ascertainthe writingend of a sheet. He must look at the sheet to see how far he has writtenand how much further he can write, (the platen is usually twirled) andthen re-locate his place in the copy or notes to go on; Writing.Sometimes it is necessary to repeat these operations, the typists guessnot being quite right'the first'tiine.

I propose to overcome these'dlflicultles by the use of a special sheethaving a projection adapted to abut or stop andgrip a part of thetypewritingfmachine; Thepaper to be written on is fed'into'the machinewith this sheet and the stop is adjtisted prs= Application filedSeptember 4, 1925.

vent, automatically, the feeding of the to in any suitable manner. In mypreferred form the base 10 consists of a sheet of material of the sizeand consistency of typewriting paper except that it should be somewhatgreater in length than the" size of the particular paper being writtenon" at the time. I do not, of course, wish to limitmyself to anyparticular consistencyor grade By automatic is meant means of material,for any that is suitable for this purpose will do; In the event,however, that very thin or flimsy material is used as the base, whichwould be preferably in manifold Work, it may be reinforced in or? derthat it may be more readily aligned with the other sheets to betypewritten before' inserting the package of sheets in the machine. Forinstance, the edge or edges 12 of the base 10 to any desired width bestiffened in any suitable manner, such as being impregnated withastiffening compound, or affixing or folding anotherjlayer of materialsothat thebas'e" will not crumple upwhen being aligned with the othersheets.

The sheet 10 may be of heavier card board when only a few-copies are; tobe struck at onee and in this casea'ifording protection to the platen131 The stop 11 is' an abutment or projection secured to the base 10and, of such size, shape and material that it cannot pass tl'irough thatpart of the typewritingmachine between the platen 1'3 and the paper feedrolls 14 after the stop has reached the platen, In my preferred form,the stop 11 may be composed of material whose surface, when abuttingagainst the platen sunface of a typewriting machine, will grip with saidplaten surface, making it impossi ble' forthe two surfaces to slide oneach other, and thus prevent feeding. I have found best results to behad, from a stop composed of yielding material, such asrubher, and ofthe shape shown in Figs. 1 and 2. The size of the" stop may be varied,and it may extend lljllef partially or wholly across the width. at thebase.

The stop 11 may be attached to the base 10 in any suitable manner,either perma nently or temporarily. I preferably use glue for permanentattachment. Wire rivets, or the like, of course, could be also used.

The point of attachment should be at a point on the base somewhat beyondwhere the bottom end of the sheet being typewritten would fall, theupper edges of the sheet and base being aligned. The exact location, ofcourse, would be determined by the amount of margin desired at the endof the typewritten sheet.

As a modification of my invention, when used in writing with varioussizes of paper and also in the event that it is desired to write a fewmore lines on the sheet while it is still in the typewriter but afterthe device has stopped the feed, I may provide a double or bellows-likefold 15 at one end of the base 10 so that the portion of the base towhich the stop 11 is attached may be unfolded and extended outwardly,the position of the stop then being beyond the line of writing.

Another modification would be to have the stop adjustable or detachable,inserting it into an opening or openings 16 in the base so as to providea flexible longitudinal margin. Graduations 17could be provided on thebase 10 so that the stop could be attached at the proper place for anysize sheet; the graduations may, if desired, correspond to the size, ininches, of the particular length of sheet being used. Any proper means,such as button 18, could be provided for attaching and detaching thestop of the base.

A further modification would be to have the graduations 17 shown at theend of the base opposite the stop 11, the stop being permanentlyattached, so that the top edge of the sheet or sheets to be typewrittencould be aligned inwardly of the base to provide for any desired margin.

Another further modification would be to have the upper part 19 of thestop detachable, and movable longitudinally of its base 20; thuscreating a flexible margin in proportion to the longitudinal movementprovided. -The stop 19 may be adjusted longitudinally of the support 20in the opening or openings 22 in any suitable manner, for instance bythe engagement of pins 21 with notches 23.

In order to assist in aligning and insert ing the sheets into thetypewriter, I may provide an inward fold 24 on the base 10 inside ofwhich fold the sheets would be inserted, thus providing for only oneedge to be inserted into the machine instead of a number of edgescorresponding to the num ber of copies being made; the result beingpractically perfect alignment.

I may also provide a suitable opening or openings 25 at any point in thebase 10 for conveniently hanging up the device when not in use.

In employing my invention, the sheet or sheets 26 to the typewritten areassembled in the usual manner, my device being aligned andplaced as thelast sheet of the package so that the stop 11 faces the platen 13 whenbeing inserted into the machine. The typist commences to write and thedevice is fed simultaneously with the sheets.

When the writing end of the sheet has been reached, the stop 11 willabut against the platen surface 13 and grip with it so that the platencannot be fed forwardly, the stop being too large to pass through thepaper feed. WVhen the typist attempts to use the line spacer to feedintothe next line after the stop has abutted against the platen, he findsthat he cannot do so, the platen and stop gripping tightly together, andnot only stopping the feeding but also the normally smooth operation ofpushing the carriage of the. machine back to the right, this operationbeing usually simultaneous with the spacing or feeding.

This gripping action is so decided and noticeable to the typist incomparison with the normally smooth operation that he knows immediatelythat the writing end of the sheet has been reached. In fact on moststandard typewriting machines the device not only stops the feeding ofthe paper but interferes with the movement of the carriage as well,until the line spacer is released.

In taking the package of sheets and the device from the machine, thesheets are pulled forwardly and the device in the opposite direction. Inmy preferred form I provide a longitudinal projection 27 on the base 11to be gripped by the typist in taking the device from the machine.

The space on the base may be used as an advertising medium, or for anyother purpose for which it may be adaptable.

I claim 1. A typewriter paper stop comprising a flexible backing sheetadapted to be assembled with the writing paper in the platen of themachine and having a projection serving to wedge behind the platen toprevent the feeding of the paper.

2. A construction of the character described in claim 1 in which atleast a part of the projection is formed of yielding material such assoft rubber.

3. A typewriter paper stop comprising a flexible backing sheet adaptedto be assembled with writing paper on the platen of the machine andhaving a wedge-shaped soft rubber projection securedto one surface ofsaid sheet near one end. I

4. A construction of the character set forth in claim 1 in which atleast a part of the projection is adjustable longitudinally with respectto the backing sheet.

5. A typewriter paper stop comprising a flexible backing sheet aprojecting member secured thereto near one end for wedging behind aplaten, said sheet extending beyond said projecting member to serve as ahandle for withdrawing the sheet.

6. A typewriter paper stop comprising a flexible backing sheet, aprojection stop member secured thereto near one end, said sheet having apocket near the other end to engage one end of a package of sheets to beinserted in a typewriting machine.

7. 'A typewriter paper stop consisting of a flexible backing sheetadapted to be assembled in the machine with the paper to be written uponand having a projecting stop near one end for engaging the platen tostop the feedingof .the sheet and the paper, and having a series ofindicating marks near the other end of the sheet for indicating theproper position of the paper with respectto the sheet to ensure stoppingthe writing of the machine whenthe paper has passed through the machinethe desired distance.

8. In a typewriter paper stop the combination of a platen, anintroductory paper guide and feed roller, a stop member and a memberconnected to the stop member and movable with the rotation of the platenfor bringing said stop member into position between said platen on theone side and said introductory paper guide and feed roller on the otherside to stop the rotation of the platen.
